RACNet: Reliable ACquisition Network for High-Fidelity Data Center Sensing
Chieh-Jan Mike Liang, Jie Liu, Liqian Luo, Andreas Terzis · 2008
RACNet is a monitoring sensor network to provide high-fidelity visibility, in terms of spatial and temporal resolu-tion, of data center environmental conditions for energy efficiency improvement. RACNet overcomes the high node density and harsh RF environment challenges in data centers to achieve over 99 % reliable data yield and short data collection latency. It does so through a novel network architecture that decouples data collection from the construction of the routing tree. This design, cou-pled with the use of different frequencies along neigh-boring data collection trees, enables RACNet to sup-port large-scale, dense networks while maintaining per-fect data reliability. Results from simulations, testbed, and real world deployments indicate that RACNet out-performs previous data collection systems, especially as node density increases. 1
